Since he decided to visit the business circle, of course Qian Rujun had to go out.

Where it is close, of course, you have to go first, so Qian Rujun will go to the central water tower area first.

Because he wants to find smart people, smart people have very good net worth and families, so Qian Rujun can't find people in the way of trying to make money and kill people, so he can only use high-level points to find smart people and use these smart people to lead everyone.

Twenty people should be enough, and he can still pay 20,000 points.

It's a pity that he can't find all smart people if he wants to find people. Because Qian Rujun estimated that to open such a workshop, at least more than 10,000 people would need to be found to process it.

Because after the gunpowder is configured, it has to go through a lot of tricks.

Therefore, if Qian Rujun wants to use all the high-level points, the number of points spent will be very terrible.

Gunpowder is a thing that has different effects if you make different tricks.

Ability to function at different times.

In this way, he could not do too much research by collecting twenty smart people, but could only have them divide the work into twenty groups to do.

In one study, there can only be twenty groups of people.

Without a computer, a lot of work takes a lot of time, which is a bit of a pity.

Gunpowder is also one of the entertainment equipment, and Qian Rujun thought of fireworks in later generations.

The Great Song Dynasty was able to play fireworks very well, and it was also hilarious for a thousand years, and it is estimated that if fireworks are generated, they probably will not make the Han people think of gunpowder.

Perhaps, they will descend on the fireworks as immortals!

It's a pity that Qian Rujun is ready to make fireworks civilian in order to earn some research funds.

The manufacture of gunpowder is a money-burning job.

The explosive power of pyrotechnics, although among gunpowder, is the weakest.

But if you want fireworks to be varied and exciting, you have to rely on design and three-dimensional imagination. in order to turn gunpowder into fireworks that can be admired.

Therefore, the composition of the pyrotechnic group must be carefully selected.

When the time comes, the ordinary people who have been collected, after low-level brainwashing training, will have to find the smartest ones from the middle and send them to the fireworks group.

Anyway, at this stage, she is only ready to bring beautiful fireworks to Dahan.

As for the Han people, whether they can see the shadow of further development from the fireworks depends on his ability.

As for the powerful artillery, bullets and stuff in the explosion.

Qian Rujun can spend more time on R&D and manufacturing. And the maker cannot be someone from the outside. Only brainwashers, that is, people from within.

In order to prevent leaks, she even asked the students of Xuetang Island not to join the work.

After all, the students of Xuetang Island have already entered the sight of the imperial court. It's not easy to dodge.

That's why she put them all out to promote the motor.

Thinking of the future, Qian Rujun sighed, if she wanted to go out, she had to carry a powerful weapon.

After facing the ferocity of the grassland people, she finally realized that even if the students of Xuetang Island who did not have the intention of killing the grassland people were relatively strong, but when they met the grassland people who were not brainwashed, they could only lose, and perhaps, they would have the opportunity to escape, even if they were lucky.

I don't know how long she can hide the craftsmanship of this kind of thing once she studies such things as artillery.

Moreover, before she left the Great Han, what she had studied, she needed to give the Great Han Emperor a point.

But her action is to hope that the Han will become stronger, but the Han has no sense of secrecy and espionage, and may soon let foreigners learn to make it.

I don't know when the Han people who love to share will learn to keep secrets.

Qian Rujun was bound to say in his explanation to the emperor that the content must be treated as a top secret.

You can't let everyone know.

But Qian Rujun also knew that in order for gunpowder to be made into practical things, it had to go through many people's processing.

So as long as you use it, leakage is almost inevitable.

Once the gunpowder spreads, the war will become extremely fierce.

In the past, the Han Dynasty only cared about fighting the Huns, and did not pay attention to Nanyue, Minyue, and Dongou and other countries.

In the same place, there are 100,000 mountains in the southwest, as well as the Tibetan people.

For the sake of the north, the south, the relatively weak people, they basically have a lot of tolerance.

Like the time of the Zhou Dynasty, Middle Earth, at most, to the south of the Yangtze River.

Qin Cai took the land to Lingnan and built a Chi Road.

However, after the Qin Dynasty arrived in Lingnan, it did not actually occupy it.

For the governance of later generations, the Qin Dynasty became an invader, and it became difficult to take back that piece of land.

The most important thing is the locals, who don't accept it.

However, in Qian Rujun's memory, this land is one of the whole of the Han Dynasty.

For those who lived in Nanyue, Minyue, and Dongou in this era, the people of their place did not recognize the rule of the north at all.

And the people here either died, or were driven to Vietnam and Malaysia, and even some people, ran to Sumatra.

And the dwarfs of Sumatra disappeared from the sight of the world, and perhaps even the bloodline was not handed down.

Qian Rujun guessed that in this era, there are also many ethnic groups, and there is no way to pass on genes to the 21st century!

It seems that genetic collection must also include the collection of human races.

But in this case, will the space accept living people?

It was also time for the Han to use troops against South Vietnam.

All this time, South Vietnam conducted various tests on the Emperor of the Han Dynasty.

But if the Han people go to the jungle in the south, one of the biggest problems is that they will have serious problems adapting to the soil and water.

What is serious? It means that a lot of people are going to die in this place.

Qian Rujun still remembers the Peony Society incident that he had learned before, when the people of the island country came ashore, they slaughtered the people of the Peony Society, and in the future they took revenge on the people of the Peony Society and hunted their heads, but the vast majority of the 30,000 people in the island country were infected with infectious diseases and died in the territory of the people of the Peony Society.

Temperate people, compared with the natives who are accustomed to the local environment, are much weaker.

He goes to the north to fight you, and he doesn't necessarily win, but if you go to the south and fight the southerners, you will definitely die.

In this era, the miasma here is not comparable to later generations.

When the canopy of the whole forest is combined, under the trees are dense vines and all kinds of plants, animals, and insects that cling to the trees.

What's more, the forest fog at this time is very heavy, because the forest has the function of retaining water, and when the forest fog floats into the air, it is easy to turn into rain.

Every tree in the forest can give birth to infinite life.

Every life has a way of self-preservation. They have to fight against powerful animals, and the evolutionary process of these life, which is not very large, is often the development of poisonous insects.

And these poisonous gases will be dispersed with the fog, and they will be dispersed with the water.

But you can't avoid poisonous water and fog when you're in the forest.

But the animals in the forest seem to be used to it, and they have a great ability to resist.

In tropical or subtropical jungles, it is only natural that these forests become the home of poison gases.

Because of the poisonous gas, the northerners, who are defenseless against the poisonous gas of these jungles, will soon decline physically, and their resistance will be even weaker.

It's just that the locals are better off in this situation, but in the poisonous forest, if they stay for a long time, they will also die.

In fact, most of the people of South Vietnam did not crawl around in the mountains, but gathered together.

It doesn't leave the place where it lives casually, and even if it does, it's just to go to the area where it lives, close to the outer forests.

But as long as the Han launches a war of conquest, you can't hide in a safe place and stay still.

Because you can't let these people go, because these people are hidden rebels, and even have a heart for their homeland.

He's hiding in safety, but you'll have to travel through the jungle to find them.

In addition to the miasma, if the dead life is not properly handled, it will produce the phenomenon of corruption due to the activity of a large number of bacteria, the Han people may know what is corrupt, but they probably do not know what bacteria are, bacteria exist in the human body, there are good and bad, the good will help you maintain your body, and the bad will accelerate your death.

And these things tend to erupt with foul odors, and these smells actually have a lot of things hidden inside.

But these corruptions or foul smells can cause many infectious diseases, such as malaria, smallpox, and plague.

It was also known as the Black Death.

Only cleanliness can keep one from disaster.

But you are the only one in the whole society, and it is useless to be clean.

People can defecate, but human feces are often the source of disease.

People die, and when people die, they can corrupt and cause crises for others.

And the hygiene standard of this era is really poor.

Perhaps, to their eyes, the water is very clean.

They don't know that so-called microorganisms are an important cause of disease in the water. And microorganisms are invisible to people.

They simply have no habit of boiling water.

It's like Europeans, who drink raw water directly.

But there is a certain reason why Europeans come to eat raw water.

The water that Europe drinks is mainly tap water, and this water, at its most basic, is disinfected with chlorine.

So the disinfection and other things are well done. Comparatively, there are very few miscellaneous bacteria in the water.

Perhaps, raw water in Europe is no different from boiled water.

I want to solve the problem that the Han people don't boil water well.

It's difficult.

Qian Rujun thought of the burning king ship in Donggang.

According to the introduction of the previous teacher, the burning of the king boat has a positive significance.

The existence of such folk festivals has led to a lot of reductions in infectious diseases.

For many diseases, fire is the best destroyer.

Flames are the best tool to deal with these miasma.

It's just that in a damp forest, setting fire to ordinary methods has a very poor effect.

However, if the explosives explode inside, it can have a certain effect in this case.

After all, explosives are meant to blow up people, and people are most afraid of setting the forest on fire.

Once you set the forest on fire, it's easy to get out.

Oil and coal can also create flames in forests.

But no matter which one it is, for Qian Rujun, the most annoying thing is that it will cause permanent pollution to the environment.

If the forest spontaneously combusts, the forest burns and leaves fertile land.

But if the oil burns, it will leave a permanent gray-black.

The damage to the forest is too great.

Perhaps, Qian Rujun will take the fire to the countries of South Vietnam!

It is estimated that few of the people who are fighting in the Han Dynasty will think of a way to set fire.

However, Qian Rujun did not think that the emperor would take her to South Vietnam.

Because, the emperor himself will not go in person.

Then, no one can control Qian Rujun in terms of status.

The Han Dynasty had many generals. Even if he is not a general, he is a lot of brave brave generals.

Zhou Yafu, before Emperor Jing of the Han Dynasty, was an important soldier.

It has not been a hundred years since he left the country, and there are still many veterans who are still alive in the court.

No matter who it is, they will think that Qian Rujun is not needed to fight a war.

It is better to ask God for your blessing than to rely on your own strength.

If his victory divides the gods, then how can they ask the emperor for credit!

Qian Rujun was able to do a good job of logistics work in the military formation.

People who have space can bring the right things. What's more, Qian Rujun not only has space, but this space can also bring her a lot of benefits.

These benefits make her perfect in logistics.

Because she can make something out of nothing.

In Emperor Liu Heng's cognition, Qian Rujun is good at logistics.

But many people will do logistics work, although it is not very good, much worse than Qian Rujun.

But on the battlefield, logistics units often do not receive the corresponding attention.

Qian Rujun walked on the street of the central water tower area, communicating with the people around him from time to time, and his ears were trying to listen to all kinds of different voices.

Because it is impossible for Qian Rujun to come forward and talk to everyone, she needs to find someone who seems to be smart from the crowd and talk to him.

Therefore, Qian Rujun can only judge from the speeches of these people whether these people are worth paying attention to, whether they are smart people or not.

Walking around the entire central water tower area, Qian Rujun found that her harvest was very good.

Walking around the street, without entering the store, you can find more than a dozen people who meet her requirements.

I don't know if the businessmen are so smart, or if the smart businessmen are all concentrated in the central water tower area.

Qian Rujun decided that she should put down the central water tower area first and go to the east and west markets of Chang'an to have a look, maybe she would get something if she went.

In the past 50 years, the merchants in the east and west have become old and time-honored businesses.

The old merchant naturally has his bearing.

Qian Rujun believes that she can make alternative and good discoveries in the East and West markets.

The only thing that makes Qian Rujun feel a little twisted, every time she enters the city, she feels very stinky.

Now coal has begun to be used in Chang'an. I don't know if coal will cause air pollution when it is used in Chang'an City.

Thinking that the air pollution in the future generations would eventually start in her hands, Qian Rujun felt very depressed.

She didn't want to, and she didn't want to use this excuse as a sacrifice for growth.

I don't know if Dahan will enact an air pollution prevention and control law.
